The GM Aero 2000, one of the most aerodynamic automobiles ever developed,
was unveiled in 1982 at the Epcot Center World of Design display.
The experimental four-seater featured sliding doors,
front wheel skirts top-hinged for access to wheels and tires,
and a speed-regulated rear foil to reduce fuel-costly air turbulence.
Many of the design concepts are evident in GM's electric car, EV1.
